Tallas en los acantilados de las calas Covas.

An emblematic and spectacular prehistoric necropolis, both for its setting and for the large number of tombs in it. They take the form of a set of cavities excavated from the rock walls of the ravines and coastal cliff faces (about 90 altogether), used by local communities to bury their dead. Several types of cave have been documented. The necropolis was used for about 1000 years, from the 11th century B.C. up until the Romans took control.

In the Roman era, despite no longer being in use as a necropolis, a series of inscriptions on the cave walls testify to their use as a place of pilgrimage, as can be seen in the famous Cova deis Jurats. Calescoves was also a major anchorage port, especially between the 4th century B.C. and the 6th century A.D., with ships arriving from powerful trading nations along the Mediterranean coast.
The caves are mostly closed off now, but if you're of an adventurous nature you can climb one of the cliffs to see this carving of the faces of two lovers. Obviously I did not take this as I'm not completely mad. Husband is though.
